Vortex flowmeters are widely used instruments for flow measurement in various industries. Based on different classification criteria, vortex flowmeters can be categorized into multiple types. Below are some common classification methods:

1. Classification by Connection Method

Flanged Connection Vortex Flowmeter: This type is connected to pipelines using flanges, making it suitable for applications requiring frequent disassembly and maintenance.

Wafer Connection Vortex Flowmeter: The body of this flowmeter does not have built-in flanges. Instead, it is clamped between two specialized flanges and secured with bolts. This structure is widely used.

Clamp Connection Vortex Flowmeter: Featuring an innovative design, this type integrates temperature, pressure, and flow signals into one unit. Using an intelligent digital processor, it combines these signals to output a compensated standard flow rate, enabling temperature and pressure compensation for gas and steam.

Insertion Vortex Flowmeter: Primarily used for large-diameter pipelines in industrial settings, this type measures the flow of gases, liquids, and steam. It is characterized by low pressure loss, a wide range of measurements, and high accuracy. Additionally, it is minimally affected by fluid density, pressure, temperature, and viscosity when measuring volumetric flow under working conditions. Its design includes no moving parts, ensuring high reliability and low maintenance requirements.

2. Classification by Detection Technology

Differential Pressure Vortex Flowmeter: This type calculates flow rate by measuring the differential pressure before and after the vortex. It is ideal for low flow rates and applications requiring high accuracy. However, some versions are designed to measure vortex shedding frequency to calculate flow, making them suitable for high flow rates and broad flow ranges.

3. Classification by Usage Requirements

General-Purpose Vortex Flowmeter: Designed for standard pipeline systems, this type has a broad range of applications.

Specialized Vortex Flowmeter: Tailored for specific fluid media or environmental conditions, these flowmeters offer higher accuracy and stability.

Explosion-Proof Vortex Flowmeter: Suitable for environments with explosive hazards.

Low-Temperature Vortex Flowmeter: Specifically designed for flow measurement in low-temperature environments.

Corrosion-Resistant Vortex Flowmeter: Suitable for measuring the flow of corrosive fluids.

4. Classification by Structural Design

Integrated Vortex Flowmeter: Combines the sensor and transmitter into a single unit for compact design and easy installation.

Split-Type Vortex Flowmeter: Features separate sensor and transmitter components, allowing flexible installation and adjustment.

5. Classification by Instrument Function

Basic Vortex Flowmeter: Provides only flow measurement, suitable for simple monitoring applications.

Smart Vortex Flowmeter: Equipped with advanced features such as temperature and pressure compensation, remote data transmission, and more, making it ideal for complex fluid control systems.

6. Classification by Measured Medium

Liquid Vortex Flowmeter: Used for measuring the flow of liquids such as water, oil, and chemical fluids.

Gas Vortex Flowmeter: Designed for measuring gas flow, including air, natural gas, and steam.

7. Classification by Installation Orientation

Horizontally Installed Vortex Flowmeter: Suitable for horizontal pipeline installation, measuring flow in the horizontal direction.

Vertically Installed Vortex Flowmeter: Designed for vertical pipeline installation, measuring flow in the vertical direction.

Q1: What are the advantages of vortex flowmeters over other flow measurement devices?
A1: Vortex flowmeters are highly reliable due to their lack of moving parts, require minimal maintenance, and offer a wide range of measurements with high accuracy. They are also less affected by changes in fluid properties such as density, pressure, and temperature.

Q2: How does a vortex flowmeter handle temperature and pressure compensation?
A2: Smart vortex flowmeters are equipped with integrated temperature and pressure sensors, which provide real-time compensation for variations in these parameters, ensuring accurate flow measurement.

Q3: What is the typical maintenance required for a vortex flowmeter?
A3: Maintenance is minimal due to the absence of moving parts. Regular cleaning and inspection of the sensor and connections are usually sufficient to ensure proper functioning.

Q4: How do I choose between an integrated and split-type vortex flowmeter?
A4: Choose an integrated flowmeter for compact and straightforward installations. For more flexible installation options or challenging environments, a split-type design is recommended.
